A survey of changes in taste and food preferences related to the coronavirus disease (COVID-19) in Hungary

A plethora of research and empiric observation supported the claim that–among other symptoms–diseases often affect the ability to smell and the sense of taste, possibly affecting the taste- and food preferences as well.The aim of the present study was to shed light on the impact of COVID-related smell- (dysosmia/anosmia) and taste function-disorder/loss (dysgeusia/ageusia) on the food and taste preferences COVID-19 patients of different symptomatic and pre-existing conditions and demographic backgrounds.The research based on a descriptive, cross-sectional survey. In total, 514 participants filled our self-administered online questionnaire. Thirteen participants were excluded according to the exclusion criteria. Descriptive statistics, Chi-square test, t-test for correlation coefficient, were performed.The most common long COVID symptom was fatigue/weakness (53.1%) followed by anosmia (50.9%) and tachycardia (33.5%). Many participants reported dysgeusia/ageusia during the acute phase of the disease, which sometimes prevailed as a long COVID symptom. A high percentage of participants reported that they rejected all kinds of meat of animal origin except cold cuts for their duration of recuperation, which proved to be the most common dietary change during the post-COVID period so far.
